| Abstract: |
| A series of experiments about the effect of the sand clay content of water and entrance pressure on the properties in hydraulics of drip irrigation tape's fine water-road resisting blockage in theory about the blockage problem were carried out in laboratory. The experiment result showed that water-road were on the half-turbulence condition and had higher transportation sand clay capability. Drip irrigation tape hardly blockage while the sand clay content of water was less than 100 mg/L. On the contrary, it began to block when the sand clay content of water was more than 100 mg/L. Its blockage degree decreased when the entrance pressure was great. |
